H. Rider Haggard 
Ivory Child [EPUB ebook] 

The timeless adventure featuring explorer Allan Quatermain, the inspiration for Indiana Jones, from one of the first authors of the “Lost World” genre.  The Ivory Child is a novel by H. Rider Haggard featuring Allan Quatermain—explorer, treasure hunter, and adventurer. In one of his strangest undertakings yet, Quatermain finds himself in the throes of a war between two African tribes, one of them led by an evil spirit that resides in the body of a gigantic elephant.   Two foreigners, Harût and Marût, call upon Quatermain by the name he uses among the Africans: Macumazana. They are convinced by divination that only Quatermain can defeat the elephant god and save Africa from an epic battle destined to plunge the continent into chaos . . .
